On February 9, 1986, Comet Halley was at its closest point to the Sun, about 9.0 × 1010 m from the center of the Sun. The average power output of the Sun is 3.8 × 1026 W.(a) Calculate the radiation pressure on the comet at this point in its orbit. Assume that the comet reflects all the incident light.(b) Suppose that a 10-kg chunk of material of cross-sectional area 4.0 × 10−2 m2 breaks loose from the comet. Calculate the force on this chunk due to the solar radiation. Compare this force with the gravitational force of the Sun.
